title: Phacomatosis pigmento-pigmentaria: should we add a new type of phacomatosis? Fact and controversies.
abstract: There are currently five types of recognized phacomatosis pigmentovascularis plus one more, phacomatosis pigmentokeratotica, making six types altogether. Should we stop here and consider the classification as being complete? Or, do we leave room to add more types or, alternatively, lump the ones we have together and shorten the list? We present our reasons for adding one or two new types of phacomatoses to the current classification, in full recognition that it is already complicated and somewhat cumbersome. We consider that the benefits of doing so outweigh any additional strain on the already complicated classification. We expect that this might not sit well with some of our colleagues, but we are prepared to do battle.
